If you have young kids, Disney will guarantee you connecting rooms.
Go with two rooms at the All Stars, you'll need the space.
A moderate will be tight with that many people and for the price of a deluxe, you might as well be honest and go to All Stars. For one night, we did squish everyone into one room - it was Thanksgiving and we had to move from All Stars because it was booked that night and this literally was the only room on property that was affordable. My son, to this day, will not let me forget - my own little Jiminy Cricket. I would do it again in dire circumstances but that's about it.
